Definitions

  • the present disclosure relates to direct device to device communications in a cellular communication network and more particularly relates to reducing interference resulting from direct device to device communications in a cellular communication network.
  • FIG. 1 illustrates a cellular communication network 10 that enables direct D2D communications.
  • the cellular communication network 10 includes a base station 12 that serves a corresponding cell 14 of the cellular communication network 10 . While only one base station 12 is illustrated, the cellular communication network 10 includes numerous base stations 12 serving corresponding cells 14 .
  • wireless devices (WDs) 16 , 18 , 20 , and 22 are located within the cell 14 . The wireless devices 16 and 18 are in proximity to one another.
  • the cellular communication network 10 assists the wireless devices 16 and 18 to establish a direct D2D communication link (i.e., a direct D2D bearer link) between one another. More specifically, through signaling with the base station 12 or some other mechanism, the wireless devices 16 and 18 discover one another using a D2D device discovery process and then establish a D2D communication link directly between one another rather than through the base station 12 .
  • Direct D2D communication is possible regardless of whether the cellular communication network 10 is Frequency Division Duplex (FDD) (i.e., uses different uplink and downlink frequency bands) or Time Division Duplex (i.e., using the same frequency band but different time slots for uplink and downlink).
  • FDD Frequency Division Duplex
  • Time Division Duplex i.e., using the same frequency band but different time slots for uplink and downlink.
  • direct D2D communication links such as that established between the wireless devices 16 and 18 , is preferably a TDD communication link where transmission by one wireless device uses the same resources as reception by the other wireless device.
  • These “resources” are physical frequency and/or time resources depending on the particular implementation of the cellular communication network 10 .
  • TDD i.e., half duplex operation
  • TDD is preferred because operating a transmitter and receiver in the same frequency band in a half duplex fashion is easier to implement than a full duplex FDD implementation.
  • the D2D communication links In order to provide spectral efficiency, it is preferable for the D2D communication links to use the same resources as those used by the cellular communication network 10 where the cellular communication network 10 performs actions such as mode selection, network-controlled scheduling, and power control.
  • the D2D communication link uses either an uplink resource or a downlink resource of the cellular communication network 10 that is also assigned to the wireless device 22 . While using the same resources as the cellular communication network 10 provides spectral efficiency, doing so also gives rise to new intra-cell and inter-cell interference situations. For example, due to the presence of D2D communication links, intra-cell orthogonality is no longer maintained.
  • the D2D communication link between the wireless devices 16 and 18 uses a downlink (DL) resource of the cellular communication network 10
  • strong intra-cell interference may be caused for the wireless device 22 , which also uses the same DL resource, as illustrated in FIG. 2 .
  • the transmissions over this D2D communication link between the wireless devices 16 and 18 may cause inter-cell interference to wireless devices located in neighboring cells in the cellular communication network 10 .
  • the case of intra-cell DL interference is displayed in FIG. 2 .
  • the case of inter-cell, or other cell, interference resulting from the direct D2D communication link between the wireless devices 16 and 18 can be easily deduced.
  • the transmission from, for instance, the wireless device 16 over the D2D communication link to the wireless device 18 using the DL resource of the cellular communication network 10 may result in interference to a wireless device located in a neighboring cell that uses the same DL resource.
  • the D2D communication link between the wireless devices 16 and 18 uses an uplink (UL) resource of the cellular communication network 10
  • strong intra-cell interference may be caused to the base station 12 serving the cell 14 for the uplink from the wireless device 22 , which uses the same UL resource, as illustrated in FIG. 3 .
  • transmission by the wireless device 16 over the D2D communication link to the wireless device 18 using a UL frequency band of the cellular communication network 10 may result in interference to the base station 12 for an uplink from the wireless device 22 using the same UL frequency band.
  • the case of inter-cell interference resulting from D2D communication using UL resources can easily be deduced.
  • Transmissions from, for example, the wireless device 16 over the D2D communication link to the wireless device 18 using the UL resource may also generate interference to base stations serving neighboring cells for uplinks from wireless devices in the neighboring cells that use the same UL resource, which are referred to herein as neighboring base stations.
  • a downlink resource of the cellular communication network is selected as a resource for a direct D2D communication link between a first wireless device and a second wireless device if at least one of the first and second wireless devices is less than a predefined threshold radio distance from a closest base station in the cellular communication network. Otherwise, an uplink resource of the cellular communication network is selected as a resource for the direct D2D communication link between the first and second wireless devices.

Similarly, the network node obtains an indication of a radio distance between a second wireless device and a base station in the cellular communication network that is closest to the second wireless device.
